Ledger Lines Explained
Ledger lines are short extra lines that extend the stave up or down. Learn the first one in each direction, add a landmark or two, and they stop being scary.
What is a ledger line?
The five-line stave is only a small window. Most instruments play higher or lower than that, so composers add short lines above or below, just for the notes that need them. A note on a ledger line is read exactly like a note on the stave: it is the next line or space in alphabet order.
Middle C: the most important ledger line
Treble clef: middle C on the first ledger line below.
Bass clef: middle C on the first ledger line above.
Middle C is the note between the treble and bass staves of the piano. It is the same pitch in both clefs, just written in two places.
Ledger lines above the treble stave
Above treble clef, the notes continue in order: the space above the top line (F) is G; the first ledger line is A; the space above that is B; the second ledger line is C. Counting up from the top line: F5, then G5 in the space above, A5 on the first ledger line, B5 in the next space and C6 on the second ledger line. The C in the third space of the stave is C5, so C6 is the C an octave above it.
Ledger lines below the treble stave
Below treble clef: bottom line E4, space below D4, first ledger line C4 (middle C), space B3, second ledger line A3, space G3, third ledger line F3.
Ledger lines in bass clef
In bass clef, the first ledger line below is E2, and above is C4 (middle C). Bass clef lines are G B D F A from the bottom; spaces are A C E G. Count up from the top line A: space above is B, first ledger line C (middle C).
Three tricks for reading ledger lines
- Know the first one. Memorise middle C and the first ledger line in the other direction.
- Count in twos. Ledger lines are every second note, so counting from the stave is quick.
- Use landmarks. High C (treble) and low C (bass) are anchors.

Frequently asked questions
How many ledger lines can a note have?
In theory many, but beyond three or four music usually changes clef or uses an octave sign (8va) to stay readable.
What is 8va?
An instruction to play an octave higher than written, so high notes do not need many ledger lines.
Which ledger line notes matter most?
Middle C in both clefs, then the first ledger line in the other direction.
